Problem statements

• Hierarchy is a central component for browsing
  online repositories in many search systems.
• Conventional search relevancy reports make users
  limit their searches to certain sections of a
  hierarchy
• Hierarchies are underutilized in the context of
  repository search

Exploratory search systems

• In Browsing and exploratory systems, it is
  important to employ faceted metadata
• Data Characteristics organized by a set of
  orthogonal attributes
• For example, Flamenco (http//flamenco.berkeley.ed
  u)

Visualization with hierarchical data

• More easy to read interface
• By interacting with both graphics and result
  cases, users can more easily explore the
  information.
• Easy way of linking the attributes of specific
  items
• Glance-able overview of the entire document space
  
• Making both cluster and outlier detection
  straightforward
• Coloring by document type

Future direction of this research

• User performance evaluation
• System enhancements
• Integration with a faceted browsing system
• Graphical enhancements
• Each faceted Resultsmaps in multifaceted
  hierarchy

Implications to our research

• When implementing exploratory search system,
  visual support is important
• Visual cue to users to navigate information space
• Helpful to grasp dominate trend of information
• System calculated weights can be applied to the
  ResultMap in a meaningful way
• How can multi-faceted information be displayed in
  a hierarchy-based visualization at the same time?
